210 hp from the factory
325 hp 6.0 liter
way more than a ford........chevy all the way
I don't think the 2008 silverado came in a 5.7 L. I could be wrong though. The 5.3 L has 315 hp and the 6.0 L has 357 hp stock.
The power rating when it was new was approximately 235-240 hp
factory it had 195hp, but probably less as mileage and wear has a way to decrease that number.
